imperfectly developed) type-specimens to examine. The species is 

 easily distinguished from O. bicolor riot only by its colour, but by 

 the straighter back of the cephalothorax. The edge of the cephalo- 

 thorax is bounded by a fine border, not by a narrow hem ("Um- 

 schlag"). C. Koch also says of his Pyth. fumosa: "Vorderleib mit 

 flaoh geschtirften Seitenkanten. The spine-armature of the legs is 

 such as L. Koch (loc. cit., p. 35) attributes to G. lapponum (L. 

 Koch), accordingly on f. inst. the tibiae of the 3 rd pair above 1, be- 

 fore 1 , 1 , behind 1 , 1 , below 2,2,2 spines. In other respects 

 this species is widely separated from G. lapponum (L. Koch), of 

 which I have seen a $ ad. kindly lent me by Dr Koch: the ce- 

 phalothorax is much narrower in front, and has black side-borders; 

 the back of the mandibles is almost straight; the area of the 4 cen- 

 tral eyes is a little broader behind than before, the legs not of a 

 uniform rusty brown colour etc. '). — In G. lapponum the cephalothorax 

 is of a dark and uniform rusty brown, the mandibles are at the 

 base prominent and strongly arched, the area of the central eyes is 

 somewhat broader before than behind; the legs appear to be shorter 

 (those of the 4 lh pair are not fully 2% times as long as the cepha- 

 lothorax); the vulva is formed by a rather large, almost ( )-formed 

 area bordered by deep furrows, which is continued behind by a small 

 lobe, and exhibits in front a large fovea. 



A specimen of the in the Fauna of Sweden previously unknown 

 G. leporina (L. Koch) (loc. cit., p. 27, Tab. II, fig. 19) from Got- 

 land, which Mr A. Stuxberg gave me, differs from G. fumosa by 

 the cephalothorax having a distinct border-hem, and by the 3 rd 

 pair of legs being of about the same length as the 2 nd pair etc. 



1) I am in possession of an interesting Gnaphosa, which perhaps is the 

 male of G. fumosa , and may here be shortly characterised : 



G. fumosa (C. Koch) ? cephalothorace , abdomine femoribusque nigro- 

 fuscis, patellis et internodiis sequentibus paullulo clarioribus, nigricanti-luridis , 

 maculis pulmonalibus testaceis; cephalothorace antice valde angustato, margine 

 tenui in lateribus limitato. — & ad. Long. c:a 6 millim. 



Forma corporis fere omnino Melanophorce Petiverii (subterraneai) , sed 

 series oculorum postica, desuperne visa, fortiter recurva. Series oculorum antico- 

 rum paullo procurva: medii eorum, diametro suo inter se distantes, minores quam 

 laterales antici, qui oblongi sunt et spatio parvo tantum a mediis remoti. Area 

 4 mediorum postice paullo latior quam antice, parum longior quam latior; medii 

 postici majores sunt quam medii antici, deplanati, transverse positi; interstitium 

 inter eos minus est quam inter medios anticos. Palporum pars patellaris dimidio 

 longior quam latior, pars tibialis hac parte brevior et, a latere visa, latior, bre- 

 vior quoque quam latior, apice supra in calcar productum forte, basi latum,
